the direction of rotation, these gases exert a lore-e o inst said vanes which acts to nrcelerute the rotation or" the wheel, at part of the lcinetic energy of the being tints con verted into pressure against the vanes. At the some time a spray of atomized water is thrown against the concave feces of the vanes, a, in a substent l sly oblique direction. A pert oi said spray of water passes out with said gases into the channels between the per-- the water, however, posses between the vanes, a, into interior of the wheel where it meets the emerging current of impure gases traveling in an opposite direction. The greater portion of this water entering bc tween the vanes, a, strikes against the concove surfaces of sold vanes :i-nd propels the wheel, I n the direction of the errow and by its inertia passes in e. iilm elong the feces oi the blades into the interior oi the said wheel. At the some time the gases which have thus been mixed with the water are thrown out between the vanes by the *entriiugel action of the some and this combined with their pressure against the nlin of water flowing along the conceve surl'eces of the vanes, serves to thoroughly interniingle the with the cold r. T this action the dust and other inn irities suspended in the will be thrown out, on action which is assisted by the deflection of the course of the hydrated gases issuing from the wheel by the stationary vanes, Z and by the impingement of this liuid mixture against the partitions, c, c, d, The fine result is that t he impurities in the will be deposited in the form of sediment at the outlet, A, to be caught, preferably, :1 water seal as usual, while the purified gases pass on. it will be noted in this example of carrying out my invention that the course of the gas is deflected, at the outer dust zone where the some are the most densely laden with impurities by reason of the greater specific gravity of those impurities, by the fixed vanes, 7), end by the inner ends otthe partitions, c, e, (Z, d, which are coiiitiguous to the wheel. Thereby the ore thrown down in tl uriurther course, per cm lerly since they is thoroughly set'urs'tet'l with water and the gases hence leave at the outlet, is, discharged of these impurities. lilorcover, it is to be observed that by the fact that the concavity oi the vanes, o, feces e direction opposite to movement of .he wheel nor 1 is site of these power to drive the wheel. Any dust which collects under the vanes rill be carried otl by the water coursing along those vanes.

in Figs. 2 and 3 is represented another form of-cnrrying out this invention. In this case the turbine wheel, L, is provided with three concentric series of vanes, e,f, g, which vanes alternately curve in opposite directions, as shown, so that in the present case the middle series of venesf, has its concavity facing in a direction opposite the direc let portion of the casing, A, said partitions ending in close proximity to the wheel and being so shaped and arranged with relation to the vanes, 6, that they will act as means for deflecting the current of gases to be purilied entering betwcen thc vanes of the wheel and issuing therefrom. In order to force the gases to llow in a substantially dioinetrical direction through the wheel, I arrange with the said wheel a. series of stationery pertitions 6, i, 7., it, whose gcneral direction is vertical and whose ends adjoining the vanes of the wheel are curved so as to make the change of direction from between the vanes to between the partitions as gradual as possible. In this modification the operation is apparent from the foregoing. The gases to be purified enter at, E, and by the partitions 6, (Z, are distributed over the lower half of the periphery of the wheelwith considerable uniformity endin their further course they pass through between the vanes on the lower portion of the wheel, thence between the partitions i, 'i, /z,,.;. c-," and thence between the vanes in the upper portion of the wheel and thence out to the outlet A between the partitions c, d, (Z. 'On entering between the vanes in the lower portion of the wheel these gases are first impelled forwsrd by the vanes, 6, whose concavity face in thedirection of rotation of the wheel, L, and the initial velocity of these combined with that of the vanes, c, eccording to numeric value and direction,

rise to e resultant velocity, which inipels these gases in their further course against the concave surfaces of the vanes, f, with a, velocity and a consequent v'zn's viva which is converted into work, in adding to the propelling power of the wheel.-' Thereby, e portion of the energy absorbed by the gases in eing hurled forward by the vanes, e, is motored sud, moreove it portion of the to the ve' ray 0:? the gases on mote";

The gas on its ent-rv into the easing and before its exit s through imnular chambers, a and (1 within whieh are arranged annularly disposed nozzles, 7a, in, for injecting or spra 'iiu the water or other wash liquid, longitudinally into the easing, said nozzles forming part of the water injeeting device, W, hero in the l'orui or" an annular tube. The nozzles "al it will be noted, are nearer to the center or axis ol the purifier than the nozzles 17: fora purpose which will he explained below. On the rotary sha t, l, are mounted a number of disks or other supports, 7r, 7:, L, on theperipheries ol' whieh are mounted the vanes or lilades Z, whose ourvi'rtnre is arrarn ed relatively as in the ease of the vanes, r of Fig. 3, the. hat in the present ease this arrangeimrnt is longitudinal instead of radial. 'lhese vanes, Z, besides the longitudinal eurvatlure just (leserihed have a ourrature in a, radial direction, as host, shown in Fig. 5, that is their outer free ends are bent over in the direction of rotation so as to prevent the water deposited on them from heing thrown againstthe walls of th easing under the aetion of the eentrit'ugal loree.

There are la sides mounted on the disks :1, series of blades or vanes, which lie onl in the outer dusty Zone ol the tlltllll. These hlades or vanes, have sueh a eurvature that they more the washing liquid in the outer dusty zone. and, in tact convey the matter aeeumulatin; in the said zone in the direction ot' l he arrows t, that is to say, opposite to the direetion in whieh the gases are conveyed h the vanes, l whieh latter direction is indi :ated by the arrows, 1?, in said l ip 5.

It will be soon from the above dcscripsion that in each of the various forms of purifier shown and dose h-cd lior carrying out this invention there are provided means for cousiug the gases to be purified to travel in one dirociion and to impart thereto 51. centrifugal movement and also means, :iing in con junction therewith, for causing the impurities or other matter collecting in the outer (lust-zone to travel in a direction opposite to the general direction iii-lion by the gases While being-purified.

While I have deseriher i herein and shown in Fig. 5 a longitudinull'r or axially acting purifier in further illustration of my invention, generically considered, I do not heroin claim the S71E18 specifically, since thus viewed it forms the subject n'mtter of El copeiuliug application.
